A team of German and Malagasy herpetologists found the brilliantly colored rainbow chameleon, now named Calumma uetzi , during an expedition to the remote Sorata massif in northern Madagascar in 2012. The males of this newly described species are usually greenish-beige with a tinge of blue on the sides of their faces, while the females are mostly brownish. But when the two sexes encounter each other, the male, in an attempt to win over the female, displays spectacular coloration, turning his body into a mosaic of yellow, red, blue-green and violet. A female that’s unimpressed changes color too, darkening her skin to nearly black, the researchers report in a new study published in the Zoological Journal of the Linnean Society
